Myvinvention relates to improvements in mechanically operated means oli opening` and closing the securing mechanism ot loose leai books, and the' like, so that leaves can be ref 6 moved and replaced, andithe objects of my invention are First:y To provide means by which the binding mechanism which secures thel loose leaves in book torni can be effectivelyl and" la very rapidly operated to release a vleaf or .tof

add a leaf to the 4bunch already'in the binding' mechanism, and

Second To provide that this maybe do-ne by` a substantially unskilledoperator, though l such binding mechanism is strong enough to hold the leaves: with considerable forcer' ItV should be mentioned thatin my con'-Y current application for a `patent of the United States tiled on theA 29th day of Jann! ary,` 1926, Serial No'. 84,598, I have' described both a sheet adapted't'or this particular purpose and ananchoring and binding mecha".-r nisiii for holding such sheets-'in bulk.

Fig. 1 is one form of the binding inechanisin re't'erred to in such concurrent application, the numbers on Fig. 1 being' the saine as those on the concurrent case,and itrep'- resents a simple i'orm o f such mechanism.

Fig.v 2 is a. perspective vien47 showing av 3o base frame adapted'forn use rWith a binder suoli as that shown in Fig. 1.

Fig. 3 isasectional side elevation of al casing built on the base frame of Fig. 2.

Fig. 4 is a plan vieiv ot Fig. 3 with' the operatingl handle inoved'thru 900. y Fig. 5 is av plan vieiv of a base plate with a inoditied form ofv n'iechanical operation adapted to deal with a plurality of binders at'the saine time. l

Fig. 6 isa section on theline VI"+VI of Fig-.1 shows a'leat'such as 1 secured on anchoring bars 16, 17, a bunch of such leaves vbeing intended-,to be'secured between they cove-rs 23 and 28, 'the bars 'being-'attached through the medium of binding plates 42,'

43 to eyes 18, 19 respectively, andthe eyes sliding on the spindle 20; this spindle 20 is Supported by hinge pieces 21, 22 attached" to the cover board 23, and riding on the spindle 20 between the eyes 18 and 19 is a helical rspring 26 tending to press the eyes 18. 19l apart.

It Will be seen that owing to the action of the' spring 26 the bars 16, 17 are'pressed .top cover board-28 is connectedrby other 42,43 so as to push out the inner'members lirinily intof'the'corners4; 5V ot the' recessed leavesl, and thii's'hold them i'roin bein'gdislodged; when itv is desired to remove 'af leail or leaves' the bars" 16, 17inust be moved toards eachotl'ier, being` attached to the eyes 1 19.

Thefanchoring bars 16, 17, inj this case madedouble bythe addition ot' the inner bars 14, 15, are made telescopic, spindles 34, 35, 36, 37v attached tobiiiding plates 40, 41.65 beiiig' airanged toslide Within ythe portions 14,*15', v16,l 17;iespectiv`ely, and' springs38, 39 being employed to draw bindingplates! 40, 41always'towards the'` binding` plates 42, 43 respectively.

The liingfedr pieces 21,y 22 Which secure the yspindle-.2O :to the cover board 23, form' stops vWhichli'init the outWard'in'oveine-nt ot' the eyes 18, 19 actuated bythe springv26. -A

hinge pieces 44', 45 Witlrthespindle 46 carry- "ing another spring 27 and working` inpre` cisely the saine Way' as the lspring 26 by pressure against eyes cairied'by' bindingv plates lhe binding` plates 40, 41actuated`by the' springs 38, 39 thus clampthe sheets` between' themselves and the binding plates 42, '43,11

to direct the covers 23, 28 of the binder so that it drops intov place correctly on the'v mechanism of theba'se tramel 50.`V

The mechanism of the base frame' isv for the *purpose of supporting `a pair of abut-V ment plates 54, moving outwardly vto separate the'binding plates 40, 41 and l42, and 43, and apair of abutment plates 56', 57 supported so as to niove inivardlythe'telescopicl bars'14, 15. The Aplates 54, y55 are `carried by guides 58, 59 Workingfinbearings 60 and 61 of the base frame, and are 'arranged so that they push against the binding plates 40, 41, and

ioo

i .shown contracted with the sheet loose inv V34, of the telescopic bars 14, 15, thus leaving the sheets loose on the co-operating anchoringbars 16, 17. These bars 16, 17 are Fig. 4.

The operation of the abutment plates 56, 57 is achieved by connecting rods 66, 67 at- Y tached at one end to the disc 65, withV 66 attached at its other end to the slide 64 and 67 attached at its other -end to the slide 63,

c these slides vworking in bearings 62 onthe base frame. The other pair of abutment plates 54,A 55 are controlled by connecting rods 70, 71 connected as to one end to points on thev disc 65 intermediate of the rods 66,

67, and on the opposite side of the disc, and the disc 65 carried bythe spindle 68 is turned by the lever 69 fixed thereon and provided with a space in the base frame for swinging through about half a circle. A feature of this swinging is Vthat thepivot ends of y the rods 70, 71 on the disc 65 are so arranged that inthe extreme yposition of the lever handle 69 the pivot ends of the links pass the-dead centre of the disc 65 and are thus locked against movement in the opposite direction when the stress of holding the plates 54, is left on the binding mechanism.

'The binding mechanism is thus held open automatically while leaves are removed or replaced. n l

` The same passing ofthe links 7 0, 71 past their dead centre on the disc. also serves yto hold together the links 66, 67 which have drawn together the abutment plates 56, 57,

thusvkeeping the anchoring bars 16, 17 out of their locking corners in the sheet 1.

In practice a bunch of sheets suchas 1 y having been secured by the binding mechanism,vcan be treated as a book and used inV the ordinary way. When leaves are required to be removed or inserted, the book 23, 28.

` is simply dropped onto-the baseframe 50,

' 55 khave pushed out the binding plates 40,

42 so as to release the sheets against the action of thersprings 38, 39 and the plates 56,y v57 have drawn in the anchoring bars 161 17. The sheets are then quite loose and can be dealt with as required, while a single return movement of the handle 69 immediately locks the whole together again as a book which can be lifted from the casing 51.

Figs. 5 and 6 show a similar arrangement of abutment plates Vbut Worked by toggle links 74, pivoted to abutment plates 76, 77, and also to abutment plates 78, 7 9V, which latter arev connected by nuts to the spindle running the full length of the base framev 81 and operating three sets of unbinding mechanisms. 1

The casings suc-h as 82, 83, 84 are all con- Vnected in similar fashion to that shown in or only one ofthe compartments 8,1, 82, 83,`

84 need be occupied, as desired. The spindle 80 is turned in its bearings by a handle 85, and the abutment plates will stay at any position in which they lare left by this handle. so that the sheets can be removed as soon as they are loose'on the anchoring devices.v
